Oh, I see custom components are in the pallete off to the left side. So then all I do is drag and drop a component in the cell and modify from there. I was looking in the file insert and everywhere but the pallete and couldn't find anything.

So a square surface area (a x a) of area a2 projected onto some cylindrical surface of radius R. So the length of one line in the square, a, projected on the surface of the cylinder is s=R*theta*2*Pi/360

Using the cosine formula to find theta in terms of R and a gives

theta=cos-1(1 - a2 / (2*R2) )

and s*a will be the area on the surface of the cylinder. So the area of a square sides a projected onto the surface of a cylinder radius R is R * theta * 2*Pi/360 *a

Based on the information you gave it sounds like it's more of a dropbox issue than a Maple issue. Dropbox is a file hosting service, so it probably just picks the first file you saved to dropbox rather than the latest version file with the same name.

I would suggest each time you save a file to dropbox, just give it a different name.
